A senior GOP Senate aide tells NRO that Senate Republicans on the Health, Education, Labor and Pensions (HELP) Committee, led by ranking member Mike Enzi, are about to send a letter to National Endowment for the Arts chief Rocco Landesman requesting “that [he] provide the Committee with information about the Agency’s involvement in [conference calls made on August 10 and August 27, 2009] and the use of taxpayer dollars for purposes other than promoting the arts and how you will prevent this from happening in the future. Please provide the NEA’s response no later than close of business on September 28, 2009.”
